在刷新应用程序池之前，.net Directory.Exists将为unc路径返回false

using System;
using System.IO;

class Program
{
    static void Main()
    {
        string uncPath = @"\\server\share\path";
        bool exists = CheckDirectoryExists(uncPath);
        Console.WriteLine($"Directory exists: {exists}");
    }

    static bool CheckDirectoryExists(string path)
    {
        try
        {
            // 尝试访问路径，捕获可能的异常
            return Directory.Exists(path);
        }
        catch (UnauthorizedAccessException)
        {
            Console.WriteLine("Access to the path is denied.");
            return false;
        }
        catch (PathTooLongException)
        {
            Console.WriteLine("The specified path is too long.");
            return false;
        }
        catch (Exception ex)
        {
            Console.WriteLine($"An error occurred: {ex.Message}");
            return false;
        }
    }
}
